My guess is that you can bolt on this system and the bike will run fine. Whether it will run better/worse than stock with/without aftermarket turning, hard to say at this point.
Gas Mileage doesn't concern me too much. I mean, it's already in the 40's. It's my guess the cb1100, like most modern engines, is tuned on the lean side. I'm just wondering how you go about richening the mixture when they put on a high flow exhaust.
Guess I'll have to wait...
